This is an experimental reference platform being deployed on KVM servers in scl1. It's based on the raw CentOS-5.5 image, and IT's puppetizing process. The idea is that, aside from getting puppet installed, the entire slave configuration is specified by puppet.

This is not tested to work as a buildslave!

From a Raw Install

scp root@buildbot-master06:/etc/yum.repos.d/* /etc/yum.repos.d/
scp root@buildbot-master06:/etc/pki/rpm-gpg/* /etc/pki/rpm-gpg/
yum clean all
yum -y update glibc yum* rhn* rpm* dnsmasq lftp mtr rsync syslinux udftools

Note that none of the above repos have an old enough version of puppet, so..

scp linux-ix-ref:/var/cache/yum/epel/packages/puppet-0.24.8-4.el5.noarch.rpm .
# get deps
yum -y install puppet
rpm -e puppet
rpm -i puppet-0.24.8-4.el5.noarch.rpm
mkdir -p /var/lib/puppet/ssl/{private_keys,certs} /var/lib/puppet/state
chown -R puppet /var/lib/puppet

Set up some stuff puppet doesn't know to set up (yet - see bug 640706)

mkdir /builds
mkdir /builds/slave
chown cltbld /builds/slave

requires using a 'kvm' class instead of 'vm' from the node, and that has some knock-on effects in other dependencies, sadly - see bug 640706

Start running puppet

puppetd --test --server=$whatever

Once that's done, make puppet and buildbot start at boot:

chkconfig puppet on

To get a working buildslave

Execute the instructions outlined in https://developer.mozilla.org/en/Linux_Build_Prerequisites, specifically:

yum install \
  cvs zip gcc-c++ glib2-devel gtk2-devel fontconfig-devel libnotify-devel \
  libIDL-devel alsa-lib-devel libXt-devel freetype-devel pkgconfig \
  dbus-glib-devel curl-devel autoconf213 xorg-x11-proto-devel libX11-devel \
  libXau-devel libXext-devel wireless-tools-devel glibc-static libstdc++-static yasm \
  mesa-libGL-devel

You then need the packages to run the framebuffer display for testing:

yum install \
  metacity xorg-x11-server-Xvfb
